ASoC: SOF: Make sof_widget_setup/free IPC agnostic

Add 3 new topology IPC ops for widget_setup, widget_free and dai_config
in order to make the pipeline management code IPC agnostic and implement
the ops for IPC3.

Use the newly introduced tplg dai_config op to configure the DAI during
BE DAI hw_params and hw_free.

Also, in preparation for IPC4, modify BE hw_params callback to skip
setting up the DAI widget. All widgets will be set up during FW
hw_params and the DAI_CONFIG IPC should be sent only if the widget
use_count is > 0. With setting up/freeing removed from the BE hw_params,
remove the configured flag as it is no longer needed.
